I canโt believe it is almost Christmas! Iโm finishing up my Christmas shopping, and I plan on spending the next week or so making food! :-) OK, I still have to work and I still have plenty of packages to wrap, but beyond that I plan on baking and cooking up a storm. I love making and delivering goodies to friends and neighbors and making meals to share with my family over the Christmas holiday. One of my favorite meals to prepare and serve is BREAKFAST! Iโve already shared my recipe for Norwegian Pancakes, which are a tradition on Thanksgiving and Christmas morning. In addition to pancakes however, we always serve a savory dish as well for those who like a little protein with their morning meal. :-)
This delicious breakfast casserole, that my mother-in-law shared with me right after I married her son, has been my go-to savory dish on Christmas morning ever since. Today I want to share it with you. Itโs perfect for Christmas morning because itโs actually BEST when made the day before.


Grandma Nystulโs Breakfast Casserole
Ingredients
- 16 slices cubed white bread
- About 2.5 pounds diced ham (I used 2, 1.25 pound, pre-cooked ham steaks)
- 1 (10 oz) can sliced mushrooms, drained
- 1 pound mild cheddar cheese, shredded
- 6 eggs
- 3 cups milk
- 1 teaspoon mustard
- 1 cup crushed corn flakes
- 1/2 cup butter, melted
Directions

Put half the bread in a buttered 9ร13 pan.


Next add the diced ham, mushrooms, cheese and the rest of the bread.

Whip together eggs, milk and mustard. Pour over the bread. Cover the casserole with foil or plastic wrap and store in the fridge overnight.

The next morning, sprinkle the corn flakes over the top of the casserole and drizzle the melted butter over the cereal. Bake at 350 for 60 minutes or until the top of the casserole is golden brown.

Let the casserole rest for a bit after you take it out of the oven. Serve and enjoy!

This recipe makes a BIG casserole so thereโs plenty to feed a crowd. It has been feeding my extended family for many years now and Iโm sure will continue to do so for many more years to come!
What is your traditional Christmas morning breakfast?

You fail to mention if this is dry mustard or prepared mustard. Can anyone answer as I am currently in the middle of preparing this dish for Christmas morning

Please log in or create a free account to comment.We usually have cinnamon rolls, hot wassail and a homemade fruit cocktail. The cinnamon rolls are the kind you let rise overnight and bake in the morning.

Please log in or create a free account to comment.I recently tried making it in a muffin pan and it turned out so well that I’m doing that this Christmas.
It cooks a lot faster than a casserole dish.
We’ll also have pancakes, extra bacon and biscuits with assorted jams and jellies.
Merry Christmas everyone!!!

Our family has two favorites we alternate between. The first is sausage, cream cheese and shredded cheddar between layers of crescent rolls. The other is a blueberry French toast.

This is our family tradition for so many years. we have made the timing later for a brunch as the grandchildren get older and have their own families. I serve a wonderful potato Casserole and a fruit compote and cinnamon rolls with the casserole. Then we open presents and seen the day enjoying toys and each other.

I thought I was the only one that served Christmas Breakfast Casserole on Christmas morning. I use Sausage and add a can of cream of mushroom soup but comes out about the same. Only now with 7 grandkids and 1 great grandson, we have had to make two big pans full, but it is looked forward to each year (the only time I serve it). Merry Christmas!
